Incident at FREDERICTON INTERNATIONAL AIRPORT

Summary

2010-05-26: MPE1525, Boeing 737 217, enroute from St. John?s (CYYT) to Winnipeg (CYWG), initially advised of an engine oil indication but then advised of a number-one engine shut down and requested to divert to Fredericton (CYFC). On the descent an emergency was declared. The flight landed safely at 13:12Z. There was minimal impact on operations.
2010-05-26: UPDATE Maintenance & Manufacturing: Oil was found leaking from around the banjo fitting. The gearbox will be replaced before the aircraft is returned to service.
2010-05-28: UPDATE TSB: A10A0053: C-GKCP, a Canadian North Boeing 737-200, operating as MPE1525, was en route from St. John's, NL to Winnipeg, MB when the crew notified Moncton ACC that had observed an oil indication problem on engine #1 (Pratt & Whitney-USA, JT8D-17A). Shortly thereafter, the crew intentionally shut down the engine and requested a diversion to Fredericton Airport. On descent an emergency was declared; the aircraft landed safely at 10:13 ADT. Subsequently, maintenance discovered an oil leak above the engine accessory gearbox oil filter. The leak was isolated to the banjo fitting of the oil line that supplies the oil pressure switch. The banjo fitting was removed and the nipple that threads into the gearbox case was removed. The o-ring between the nipple and the gearbox was found to be severed. The surface of the gearbox case that the o-ring seats against was pitted and showed signs of deterioration. Prior to further flight maintenance will replace the gear box due to the uneven sealing surface of the gearbox boss which could possibly result in a future o-ring failure.
